The piezoelectric phenomenon has garnered enough techniques for different types of products. Manufacturers have gone a step ahead with developing different kinds of piezo components so that they can be used for different acoustical purposes. Such acoustical applications have evolved the piezo sounders and speakers.
In actual the piezo sounder converts the electrical signal into sound. It is also used to generate audible beep sounds. With the availability of multi piezo elements and components in the markets, there are certain products that have gained prominence in demand as well as manufacturing like: piezo buzzers, piezo discs, piezo speakers, etc.
There are basically two types of piezo acoustic generators: the 2-terminal types and 3-terminal types. In both of them, a piezo element is mounted on the diaphragm. In general, the diaphragm is made up of stainless steel, brass or any other metals. When alternating voltage is applied through the piezo ceramic element, the alternating expansion and contraction of the piezoceramic element takes place which results in the movement of the membrane and hence generates the sound waves.
The piezo speakers and sounders have multi-applications like:

The piezo speakers and sounders have multi-applications like:
- Car horns
- Microwave ovens and other household appliances
- Alarms like fire alarms, burglar alarms, gas leakage alarms
- Smoke detectors
- Telephone ringers
- Confirmation sound of other audio components, etc.
